CHECK THE ENTRY UNLOCK FUNCTION

(a) Check the entry unlock function (driver door, front passenger door).

(1) Perform a wireless lock door operation to lock the door, touch the unlock sensor built into the backside of the front door outside handle assembly of the driver door while carrying the electrical key transmitter sub-assembly and check that the door unlocks.

(2) Inspect the entry unlock detection area. Hold the electrical key transmitter sub-assembly at the same height as the door outside handle assembly and approximately 0.7 to 1 m (2.30 to 3.28 ft.) from the vehicle as shown in the illustration and check that the LED (red) of the electrical key transmitter sub-assembly blinks.

*a

0.7 to 1 m (2.30 to 3.28 ft.)

(3) With the system in unlock standby mode, grasp the front door outside handle assembly (for driver door) and check that the door unlocks.

HINT:

  • The system is in unlock standby mode when the electrical key transmitter sub-assembly is in the detection area and the key ID code sent by the electrical key transmitter sub-assembly matches the key ID code stored by the certification ECU (smart key ECU assembly).
  • Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the door outside handle assembly.
  • Inspect the front passenger door using the same procedure.

(4) Check the unlock response sensitivity. With the system in unlock standby mode, touch the area shown in the illustration and check that the door unlocks.

NOTICE:

If the sensor is touched too quickly or released too slowly, the sensor may not react and the door will not unlock.

*a

Unlock Sensor (Backside)

HINT:
